i The main switch and principal parts of 30 the distributing mechanism are enclosed in a casing usually mounted in a vertical position 11 the face of a board. This casing is com posed of a bottom 1, sides 2 and upper and lower ends 3 and 4 respectively. A flanged cover 5 is pivoted by means of hinges 6 at the lower end and has a recess 7 Fig. 1, communicating with a slot 8 passing through the flange of the cover and the side wall of the box for attachment of a seal or lock. The upper end wall is provided with an opening for the end of the meter casing 9.

Within the casing of the switch mechanism the parts are carried on a porcelain base 10. Mounted on the bottom of the easthe customers fuse "erminals 11 and 12. The terminal 11 com- .nunicates with one terminal of a'companys fuse 13, the opposite terminal of whichcommunicates througha plate 14 with the ter- 6 by the crank portion 19 of a switc operating, at the upper. end of the service side, are.

ing rod 20 which site sides of the vided with. an operating arm 21.

On the customers side of the base 10 there are mounted the distributing arrangements consisting of terminals 22 and 23 connected by an auxiliary switch 24 which can be opened by hand when the cover of the box is lifted, for meter testing operations. On this side also there is a twin terminal 25 connected 'by a plate 26 to a terminal 27 adapted for connection to the ground. And on the plate 26 are binding screws 28 and 29. Various other arrangements of terminals and switches may the character of the current and the customers requirements. The lower end of the main casing is provided with an opening 30 for access to the terminals of customers fuses. These fuses are carried in a casing comprising a bottom 31 flush with the bottom of the main casing, sides 32, a lower end wall 33 and an upper end wall 34 which has an opening communicating with the opening 30 into the main casing. On the front of this fuse casing is a cover 35 flanged at its lower and side edges and mounted on such side edges by means of hinges 36 at the upper edge of the cover. e

'Within this casing is a porcelain block 37 passes through the op carrying the fuse sockets and terminals.

The block 37 is provided at its opposite sides with ears 38 perforated to carry a bolt 39 and is provided with a shoulder 40 for engagement by a nut 41 to prevent rotation of the latter. The corresponding side portions of the lower end 4 of the main casing and of the upper end 34 of the fuse block casing are provided with slots through which the bolt passes .with its head on the inside of the main casing. Thus the block 37 is fastened in place and the main casing and the auxiliary casing are fastened together, all by the same fastening means, and this fastening means is operable only from the inside of the main casing which is under controLof the company. When the main casing unfastened to obtain access'to the switch and distributing mechanism within the main casing to steal current.

One terminal of each socket is connected casing and at one end is probe employed according to is locked the auxiliary casing cannot to the corresponding terminals of the other by a plate 42 connecting by a plate 43 to a terminal 44 on the upper portion of the block 37. The other terminals of the two fuse sockets are connected separately to terminals 45 and 46 alongside the terminal 44. See Fig. 4.

The upper face of the block 37 is substantially flush with the lower end wall 4 of the main-casing so as to close the sides and the forward edge of the opening 30, the lower edge thereof being closed by the meeting of the bottoms 1 and 31 of the two casings. The terminals 44, 45 and 46 are accessible only from the inside of the main casing. To permit the use of a block which is flush with the lower end wall of the main casing, the terminals 44, 45 and 46 are set on an inclination so that the binding screws thereof are tilted toward the inside of the main casing andcan be easily operated by a screw driver in the position shown at 47, Fig. 3. This flush arrangement of the auxiliary devices leaves the entire inside of the main casing clear for wires and whatever mechanism is desired therein.

The wiring of the apparatus thus described, for a two-wire system, is indicated in Fig. 4. The service wire 48 passes to the terminal 12, thence by Way of the company fuse 13 to the terminal 11 and by wire 49 to a coil 50 of the meter; whence a wire 51 leads to the terminal 22 of the distributing devices. The current passes through the switch 24 and terminal 23 to a wire 52 leading to the central terminal 44. The arrangement illustrated is for two circuits to be used by the customer, in whichcase both the customers fuses will be used. The current passes from the terminal 44 to the fuse 53 and thence to the wire 54 of what we will call the customers circuit 1Y0. 1. The current passes also from the terminal 44 through-customers fuse 55 to the wire 56 of the customers circuit No. 2. The return wires 57 from customers circuit No. 71, and 58 from customers circuit No. 2, are connected to the terminals 28 and 29 leading to the twin terminal 25 to which is connected a branch 59 leading to the meterand a second wire 60 constituting the neutral of the service line. Y r

The service and the customers wires will enerally pass out through openings in the sides of the box which are provided with knock-outs for the purpose as is usual in the art. The lower end wall of the box may also be made with certain knock-outs which adapt it for use with the customers fuse block as shown, oruwithout such use. The fuse block and its casing may be a separate article in production and also in commerce adapted for application to maincasings of the character illustrated wherever such application is desired. It may be applied in other positions, but the position on' the lower end of the main casing .is par- 'ticularly advantageous because it facilitates the connections and does not interfere with any of the parts of the usual arrangement. It is made comparatively.

Generally the cover of the fuse casing will not be locked. In fact the principal function of this casing is to prevent accidental injury to the'projecting block 37 of porcelain.

giving easier access to the And though we have called it a casing, it

may be a mere frame serving to protect the porcelain block toa greater or less extent.

5 illustratesa modification of this" casing in which it comprises a back wall 31,

Fig.

side walls 32, upper end wall 34 and cover 35, all as in the previous figures, but has no lower end wall 33. It is very unlikely that the porcelain will be struck a blow from the underside. Therefore this arrangement gives practically complete protection.

: Fig. 6 illustrates a modification in which side walls 32 are used of approximately the same width as the shoulderedupper portion 38 of the porcelain block, "an end wall 34 similar to that of the previous figures and a back wall 31 which is cutraway so that it is approximately the sameshape as the back face of the porcelain ing or frame may be used with or without a hinged cover (and the same is true of the several other designs illustrated).

Fig. 7 is a design which is still further reduced, having sides 32 and anupper end wall 34 as in Fig. 6, and no back wall or lower end wall. We might go to the extreme limit and omit the casingentirely from the porcelain block, though I prefer at least the protection offered by the arrangement of Fig. 7, with a hinged cover like 35, Fig. 3.

The invention is applicable not only to the type of fuses illustrated, but to fuses and sockets or terminals of various other types and in fact to various cut-out devices other than fuses. The invention contemplates also the connection of the fuse block or its casing not diretly to the casing carrying the switch butto any extension'thereof under control of the company as to accessibility, such extension being for the purposes of this the particular embodiments disclosed. Various modifications may be made .by those block. This castherefrom that the invention'is restricted to j skilled in theart without departing from defined in the following the invention as claims. 7

What I claim is: 1. In combination, a scalable main casing having an aperture in one wall, an auxiliary casing having an aperture in one wall similar to the aperture in the main casing, the

auxiliary casing being positioned adjacent the main casing with the said apertures coinciding, a fuse block in the auxiliary casing having wire terminals positioned to be accessible only through the coinciding apertures, fuse receptacles on the block positioned to be accessible from the outside of the main casing and fastening meansengag? ing the casings and the blockand positioned to be operable only from within the main' casing.

jacent the main casing with the said apertures coinciding, a fuse block in the auxiliary casinghaving wire terminals positioned to be accessible only through the coinciding apertures, fuse receptacles on the block positioned to be accessible only in the auxiliary casing and common fastening means engaging the casings and the block and positioned to be operable only from withinthe main casing.

3.'An apparatus of the character described including in combination a main casing having an opening and an auxiliary cut-out device adjacent to the box and having terminals located outside of the main casing in register with said opening and inclined so as to face toward the front of the main casing, said terminals being positioned to be operable only from within the main I casing.

In witness whereof, I have hereunto signed my name. a i
